General Description
The TQM879026 is a digital variable gain amplifier
(DVGA) featuring high linearity and digital variable gain
control in 0.5 dB step sizes. This DVGA integrates a
gain block, a digital-step attenuator (DSA), and a high
linearity ¼-watt amplifier into a compact 4x4 mm
package. The internal 6-bit DSA provides a 31.5 dB
gain control range and is controlled with a serial
periphery interface (SPITM). The individual stages are
accessible to external ports to allow for optimization of
the last stage amplifier for individual bands and also
allowing other functional blocks to be added in-
between the stages.
The TQM879026 features variable gain from 1 dB to
32 dB at 2.14 GHz, +42.5 dBm output IP3, and +24
dBm P1dB while only consuming 176 mA current from
a 5V supply. The module is available in a compact 24-
pin 4x4 mm leadless SMT package.
